The Eighteenth-Century Poetry Archive (ECPA) is a digital project in support of the teaching, study, and research of the poetry of the long eighteenth century. It comprises a full-text collection of richly-encoded digital texts and a research project that aims to integrate texts and (digital) scholarship into a curated research collection. ECPA is based on the principle of user participation, the corpus is edited and annotated collaboratively, and will grow and evolve with the requirements and interests of its users.
